coronary syndrome collagen congenital

BACKGROUND: Dilated coronary arteries, coronary blood flow, and the paucity of coronary atherosclerosis have not been studied in cyanotic congenital heart disease. METHODS: Coronary arteriograms were interpreted in 59 cyanotic adults, and dilated coronaries were examined histologically in 6. Coronary blood flow was determined with N-13 ammonia positron emission tomography in 14 Eisenmenger syndrome patients and in 10 controls. Total non-fasting cholesterols were retrieved in 279 patients who were divided into: Group A--143 cyanotic unoperated, Group B--47 acyanotic after operation, Group C--41 acyanotic unoperated, Group D--48 acyanotic before and after operation...

In this comprehensive review of matrix remodeling, one central theme that bears re-emphasis is the extensivecross-talk and dynamic interactions that exist between terminally differentiated, postmitotic cells, proliferative cells, and the ECM of the cardiovascular system. The activities of MMPs and TIMPs constitute a well-orchestrated contest to maintain tissue integrity and homeostasis. Overexpression of MMPs tilts the balance in favor of irreversible tissue destruction of joints (eg, as in rheumatic disease), and efforts to curtail such errant pathways are ongoing (123)...

Supravalvar aortic stenosis is a rare congenital heart anomaly, producing left ventricular outflow tract obstruction. Of the two anatomic variants that have been described, diffuse type is the rarest. We report five such cases in children between two months and nine years of age. None had features of Williams syndrome. The entire aorta was involved in three cases, with abdominal aortic coarctation in two cases. Stenosis was mainly due to involvement of the media, which showed smooth muscle hypertrophy, abnormal elastic fibers, and mild collagenization...

The clinicopathologic findings of 23 patients with cardiac fibroma are presented. The mean patient age was 13 years, with a range of 1 day to 56 years. The presenting symptoms included heart failure, arrhythmias, sudden death, cyanosis, and chest pain. Some patients had no symptoms, and one patient had Gorlin's syndrome. Echocardiography and magnetic resonance imaging were very sensitive in diagnosis. Nineteen patients underwent tumor resection or biopsy, and four tumors were diagnosed at cardiac transplantation or autopsy on explanted hearts...

A report is given on all 11-weeek-old male child who, after normal development, suddenly became critically ill and died within 8 hours. The autopsy revealed a rare aetiologically and in its pathogenesis unclarified, always lethal clinical picture of so-called "Arteriopathia calcificans infantum" (ACI). An analysis of 90 published cases revealed an average age of the diseased children of 150.9 days and a mean duration of the disease of 32.8 days; in the large majority of the cases (64.7%), death occurred at the latest within 3 days of the first symptoms...
